Objectives: To study the comparative effectiveness of dexamethasone vs prednisone/prednisolone in children hospitalized with asthma exacerbation not requiring intensive care.
Study design: This multicenter retrospective cohort study, using the Pediatric Health Information System, included children aged 4-17 years who were hospitalized with a principal diagnosis of asthma between January 1, 2007 and December 31, 2012. Children with chronic complex condition and/or initial intensive care unit (ICU) management were excluded. Propensity score matching was used to detect differences in length of stay (LOS), readmissions, ICU transfer, and cost between groups.
Results: 40,257 hospitalizations met inclusion criteria; 1166 (2.9%) received only dexamethasone. In the matched cohort (N = 1284 representing 34 hospitals), the LOS was significantly shorter in the dexamethasone group compared with the prednisone/prednisolone group. The proportion of subjects with a LOS of 3 days or more was 6.7% in the dexamethasone group and 12% in the prednisone/prednisolone group (P = .002). Differences in all-cause readmission at 7- and 30 days were not statistically significant. The dexamethasone group had lower costs of index admission ($2621 vs $2838; P < .001) and total episode of care (including readmissions) ($2624 vs $2856; P < .001) compared with the prednisone/prednisolone group. There were no clinical significant differences in ICU transfer or readmissions between groups.
Conclusions: Dexamethasone may be considered an alternative to prednisone/prednisolone for children hospitalized with asthma exacerbation not requiring admission to intensive care.
